ARKI (Arctic Offshore Structures) is a domestic
study pursuing research on ice engineering technology that was started at VTT twenty years
ago. The project is financed by the National Technology Agency of Finland (TEKES), the Finnish Maritime Administration, the Finnish Road Administration and the Technical
Research Centre of Finland (VTT). The
project supports VTT's participation in international co-operation on ice engineering
research. The objectives include transfer of the state-of-the-art information for Finnish
companies developing marine structures for ice-bound waters. A material model has been
developed for the numerical simulation of the ice failure processes (See Publications).
STRICE (Measurements on Structures in Ice) is a follow-up study for the LOLEIF project. Pre-normative research was carried out by continuing full-scale measurements in the Gulf of Bothnia in 2001-2003. The full-scale data will be released for publicity in 2009. Public-domain information is available in STRICE web-pages and in the Publications-page.
COSAR (Choise of Arctic Offshore Structures) and INTAS 97-1665 (Reliability of Engineering Facilities in the Arctic Seas) were two subsequent research projects funded by INTAS. VTT co-ordinated the work of five institutes from Norway, Russia and Ukraine to improve models that are used to determine ice loads on Arctic Offshore structures. Basic information on these projects as well as selected papers are available in the INTAS Publications-page.
NEST (Networking Studies on Ice and Compliant Structures) is an EU funded network project to stimulate co-operation and to change information between European and Chinese researchers. The project concentrates in studies of ice-induced vibrations of offshore structures. New full-scale data on vibrations of vertical as well as conical structures is availalable in the Publications-page.
VIBRA (Ice Induced Vibrations of Marine Structures) is an experimenal study supporting the projects ARKI and NEST. Tests were made in the ARCTECHLAB at the Hamburg Ship Model Basin in 2002 using a test structure that was sensitive to ice-induced vibrations. The work was financially supported by the Human Potential and Mobility Programme from the European Union through contract HPRI-CT-1999-00035. The test report and conference papers describing the tests are available in the Publications-page.
